Am sorry, You must have mistaken.. This is not to scam and I don't intend to do that. I am just a student and am doing a project in which myself or my mate will have to recieve notification with required information through a phone call, in case an exception occurs.
A phone call with a voice message sounds very 80s or early 90s to me.
Rather than calling and trying to play pre-recorded message, consider sending an SMS or email message.
